MANUALE D’USO E MANUTENZIONE
GENERAL
The electronic controllers of the PLUS 200 series have been designed to control static or
ventilated cold rooms.
The PLUS200 2 PLT electronic panel allows the user to control all the components on a
refrigeration unit equipped with a double system. The panel allows the user to control the
essential components of a refrigeration system with up to two compressors, a double
evaporator (fans and defrosting elements) and a cold room light.
The double evaporator is controlled separately with a double defrosting sensor.

MANUALE D’USO E MANUTENZIONE
IMPORTANT INFORMATION FOR THE INSTALLER
1. Install the device in places where the protection rating is observed and try not to
damage the box when drilling holes for wire/pipe seats.
2. Do not use multi-polar cables in which there are wires connected to inductive/power
loads or signalling wires (e.g. probes/sensors and digital inputs).
3. Do not fit power supply wiring and signal wiring (probes/sensors and digital inputs) in
the same raceways or ducts.
4. Minimise the length of connector wires so that wiring does not twist into a spiral shape
as this could have negative effects on the electronics.
5. Fit a general protection fuse upstream from the electronic controller.
6. All wiring must be of a cross-section suitable for relevant power levels.
7. When it is necessary to make a probe/sensor extension, the wires must be of the
correct cross-section, which in any case must be at least 1 mm2.
STANDARD ASSEMBLY AND USE KIT
The PLUS 200 2 PLT electronic controller is supplied with the following assembly and
utilisation items:
•N°3 sealing gaskets to be placed between fixing screws and box backing
•N°3 NTC temperature sensors (room, evaporator 1, evaporator 2)
•N°1 user’s manual.

FUNCTIONS CONTROLLED BY THE PLUS200 2 PLT
-Display and adjustment of room temperature
-Display of evaporator 1 and evaporator 2 temperature
-System control activation/deactivation
-Operation with single set-point and control of two motor condensing units with delays
between the two parameter-set starts.
-Compressor rotation (to make wear uniform)
-Operation with double set point for gradual application of refrigerating power
-System warnings (temperature sensor error, min-max temperature alarms, compressor
1 and compressor 2 safety devices)
-Evaporator 1 and evaporator 2 fan control
-Automatic/manual defrost control (static, with elements, cycle inversion)
-Clock for real time clock defrosting of the two evaporators simultaneously or separately
(even where defrosting cycle is set simultaneously the end-of-defrost temperature and
control of fan start delay on the two evaporators are independent)
-Room light can be switched on with on-panel key or door switch
-Alarm relay
